Dependence of energy barrier reduction on collective excitations in square artificial spin ice: A comprehensive comparison of simulation techniques
Sabri Koraltan, Matteo Pancaldi, Naëmi Leo +9
We perform micromagnetic simulations to study the switching barriers in square artificial spin ice systems consisting of elongated single domain magnetic islands arranged on a squa…
Hybrid FFT algorithm for fast demagnetization field calculations on non-equidistant magnetic layers
Paul Heistracher, Florian Bruckner, Claas Abert +2
In micromagnetic simulations, the demagnetization field is by far the computationally most expensive field component and often a limiting factor in large multilayer systems. We pre…
Micromagnetics and spintronics: Models and numerical methods
Claas Abert
Computational micromagnetics has become an indispensable tool for the theoretical investigation of magnetic structures. Classical micromagnetics has been successfully applied to a…
Large Scale Finite-Element Simulation of Micromagnetic Thermal Noise
Florian Bruckner, Massimiliano d'Aquino, Claudio Serpico +3
An efficient method for the calculation of ferromagnetic resonant modes of magnetic structures is presented. Finite-element discretization allows flexible geometries and location d…
GPU Accelerated Atomistic Energy Barrier Calculations of Skyrmion Annihilations
Paul Heistracher, Claas Abert, Florian Bruckner +2
We present GPU accelerated simulations to calculate the annihilation energy of magnetic skyrmions in an atomistic spin model considering dipole-dipole, exchange, uniaxial-anisotrop…
A fast finite-difference algorithm for topology optimization of permanent magnets
Claas Abert, Christian Huber, Florian Bruckner +3
We present a finite-difference method for the topology optimization of permanent magnets that is based on the FFT accelerated computation of the stray-field. The presented method e…
